Abstract: PURPOSE:To sufficiently secure the stirring time of developer and to obtain a high-quality image even when a developing device is miniaturized by separately arranging the developing device and a toner replenishment means by using a toner carrying means and making the toner carrying means from a metallic pipe. CONSTITUTION:The developer for developing an electrostatic latent image is housed in a developer container 1, uniformly carried inside the container by the rotation of a carrying screw 2 and supplied to a developing roll 3. When toner is consumed and the concentration thereof becomes thin, it is detected by a toner concentration detector 4 and transmitted to the toner cartridge driving means of a toner cartridge 5 as an electric signal. Then, a stirring blade 6 is actuated. By the rotation of the blade 6, the toner housed in the cartridge 5 is stirred and sent to a toner carrying pipe 7. Since the pipe 7 is a metallic pipe, the desired electrostatic charge quantity of the toner is obtained while the toner is carried toward the container 1 by the triboelectrification of the toner and the pipe 7.

Title: Method for measuring direction of signal
Inventor: INAGAKI EIICHI
IPC: G01S3/802
Filed: 1994-04-27
Abstract: PURPOSE:To improve the measuring accuracy of direction of a target signal. CONSTITUTION:A signal spread in an acoustic medium is received by wave detectors 1-i (i=1 to N) and converted into an electric signal. A wave-receiving surface from a target of the wave detector located at the center of the wave detectors 1-i is taken as a phased surface by a phasing device 12. A sum (tauik+DELTAtauik) of a propagation time tauik between each wave detector 1-i and the phased surface to each of a plurality of estimated directions tauk (k=1-m) and a correction value DELTAtik of the propagation time stored in a propagation correction value table 11 is obtained on an assumption that the target is propagated at the same speed inside and outside an acoustic dome. The electric signal output from each wave detector 1-i is corrected by the sum (tauik+DELTAtik). A sum of the corrected electric signals is output to a direction-measuring device 3 as a beam of the direction thetak. The direction-measuring device 3 obtains direction of the maximum power among the receiving beams for every direction, and outputs the direction as a direction of the target.

Filed: 1990-04-05
Abstract: A refractory assembly includes a refractory outer member (1) having therein an opening (2) defined by an inner surface and a refractory inner member (3) having an outer surface. The dimension of the outer surface of the inner member is greater than the dimension of the inner surface of the outer member by an amount of from 0.05 to 0.15 mm. The outer member is heated to at least 1000°C to thereby increase the dimension of the inner surface.
